"The Kraken" is the 305th military intelligence battalion. Sidneys' source is from this military battalion - along with other sources he doesn't want to talk about.

Also straight after the kraken talk, he talks about the servers being seized in Germany inside a CIA facility.

"I've heard it didn't go down without incident" Initial report says US soldiers were killed in that operation (but he hasn't been able to verify it).
